This invention relates to means for thoroughly breaking up the particles of liquid fuel usually permitted to enter the cylinders of an internal combustion engine, thereby supplying .a more homogeneous mixture to the engine withthe result of a saving of fuel a u1cker and more res JOIlSlVG ex 310- 'sion, an increase in power and a complete While the drawings illustrate preferred 'embodimentof the invention, it is to be understood that in adapting the means to meet specific needs and requirements, the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the'merits thereof, reference is to be had to the following description and "the drawings hereto attached, in which,

Figure 1 is a central, longitudinal sectional view of a device embodying the invention.

- Figure 2 is a top plan view of the device, showing the diametrical cutin the gauze screen preliminary to deflecting the portions bordering upon the cut to form the inner deflecting walls of the pockets.

Figure 3 is a view similar to Figure 2, after the edge portions of the gauze screen adjacent the out have been deflected.

Figure 4 is an edge view of the device.

Figure 5 is a detail sectional view showing the device in operative position.

Figures 6 and 7 are obverse and reverse perspective views of thedevice.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The numeral 1 designates the inlet of an intake manifold of an internalcombustion engine and 2 the outlet of acarbureter. 'rts may be of any well known con i and are illustrated to demonstrate the application of the invention. The contiguous ends of the parts 1 and 2 are formed with outer flanges 3 which are apertured to receiveconnecting bolts 4. This arrangement is ordinary. The numeral 5 designates the usual butterfly valve provided in the outlet of a carbureter for controlling the flow of the mixture therefrom to "the intake manifold. of the engine.

' In accordance with the present invention the device comprises an elongated flat body 6 corresponding to the usual gasket which is placed'between the flanged ends 3 o'f'the carbureter and intake manifold. This fiat body is provided in opposite end portions with openings 7 for passage of the bolts 4,

and has a central opening 8 coinciding with the openings of the parts 1 and 2 .for passage therethrough of the gaseous mixture.

A gauze screen 9 extends over the opening 8 and maybe securedto the flat-body :6 in any determinate way. Usually,the body 6 comprises companion partsor plies, and the gauze screen is secured between such'parts or plies, in any 'preferredwa-y. The portion of the gauze screen opposite the opening '8 is pressed into concavo-convex 7 form ;to provide a dome-shaped screen. A diametrical cut 10 is formedin the dome-shaped screen 9 and extends transversely of the body to within a short distance 'of the circumference thereof. This is indicated most clearly in Figure 2. The edge portions of the screen bordering. upon the diametrical cut- 10 are deflected away from the flatbody in the same direction to form walls 11 which 1,629,964 PATENT oF icr...

are perpendicular to the body. The walls the latter curving from the plane of the body 6 to thetop of the walls 11, whereby to deflect the gaseous mixture towards the opening 12 where it is arrested by the walls 11, and deflected in a reverse direction, before escaping through the opening 12. This is indicated most elearly in Figure 5 of the drawings; a. pariah. of the gaseous mutate passes through the infinitesimally small meshes of the gauze screen, thereby breaking up any particles of the liquid fuel contained therein. However, the major portion of the gaseous mixture is deflected by the walls 11 in a reverse direction before escaping through the opening 12. The agita tion produced by deflecting the gaseous mixture results in a breaking up of any particles of liquid contained therein, so that a homogeneous mixture is supplied to the engine with the result of more power, a,

around the outer edges of the wings of the valve when the latter is open, as lndicated by the arrows in Figure 5, and the mixture is directed into the outer side of the pockets 13 and caused to approach the inner walls 11 which deflect the mixture in a reverse dircction, prior to its escape through the opening 12 to enter the intake manifold 1 on its way to the engine.

Having thus described the invention, I claim:

1. A device for breaking up particles of liquid fuel preliminary to the entrance of such fuel into the engine, the same comprising a fiat body having a centrally disposed opening, and a gauze screen fitted in the opening of the body and comprising oppositely disposed pockets facing in the same direction and separated by a diametrical opening, the outer walls of the pockets curving from the circumference o'l the opening oi the body towards one another and the inner walls being approximately perpendicular to the body.

A device For breaking up particlesoi liquid fuel and adapted to be interposed in the length of the intake manifold of an internal combustion engine, the same comprising a flat body having a centrally disposed opening and a gauze screen fitted to the opening of the body and comprising oppositely disposed pockets of approxiimltely crescent form and separated by a dian'letrical opening of ellipti'al outline. said pockets facing in the same direction and their outer walls curving and their inner Walls being substantially perpendicular to the plane of the said fiat body.

3. A fuel mixer "for an internal combustion engine, the same con'iprising an elongated flat body having a centrally disposed opening and adapted to be interposed in the length of the intake manifold, and a gauze screen applied to the opening of the body and comprising oppositely disposed crescent shaped pockets separated by a diametrical opening of elliptical outline, and having the outer walls of the pockets curved symmetrically and having the inner walls perpendicular to the plane of the body.

In testimony whereof I affix my signature.
